Alzheimer's Disease News and Research

RSS

Alzheimer's disease (AD) is an irreversible, progressive brain disease that slowly destroys memory and thinking skills and, eventually, the ability to carry out the simplest tasks of daily living. In most people with AD, symptoms first appear after age 60. AD is the most common cause of dementia among older people, but it is not a normal part of aging. Dementia refers to a decline in cognitive function that interferes with daily life and activities. AD starts in a region of the brain that affects recent memory, then gradually spreads to other parts of the brain. Although treatment can slow the progression of AD and help manage its symptoms in some people, currently there is no cure for this devastating disease.

Aging gracefully requires taking out the trash

Suppressing a cellular cleanup-mechanism known as autophagy can accelerate the accumulation of protein aggregates that leads to neural degeneration.

Data suggests chromium picolinate may improve cognitive function

Nutrition 21, Inc. has announced the results of a clinical study that showed daily supplementation with 1000 mcg of chromium as chromium picolinate improved cognitive function in older adults experiencing early memory decline.

Immune system may target some brain synapses

A baby's brain has a lot of work to do, growing more neurons and connections.

Nematodes provide clues to dopamine's role in human aging diseases

Research carried out with a paintbrush bristle, a metronome, smelly chemicals and thousands of microscopic worms called nematodes may reveal important information about human aging diseases like Parkinson's and Alzheimer's, thanks to a grant from the Ellison Medical Foundation awarded to a University at Buffalo neurobiologist.

Lipids in the brain an important factor for Alzheimer's disease

As the most common form of dementia in the Western world, Alzheimer's disease carries enormous implications for our ageing society.

Hypertension associated with risk for mild cognitive impairment

High blood pressure appears to be associated with an increased risk for mild cognitive impairment, a condition that involves difficulties with thinking and learning, according to a report in the December issue of Archives of Neurology.

Sugary drinks may increase Alzheimer's risk

Excess drinking of sugary beverages like soda may increase the risk of Alzheimer's disease, suggests new research in mice.

Regular exercise helps reduce the risk of Alzheimer's, depression and dementia

British researchers from Bristol University say following a regular exercise programme can significantly reduce the risk of Alzheimer's disease by as much as a third.

Older brains out of sync - memory and reasoning impaired

According to new research from the U.S., as people get older communication between different regions of the brain breaks down.

Growing old can affect the higher-level brain systems that govern cognition

A team of Howard Hughes Medical Institute researchers has shown that normal aging disrupts communication between different regions of the brain.

Missing brain protein may be one of the culprits behind autism and other brain disorders

The protein helps synapses develop. Synapses--through which neurons communicate with one other-underlie our ability to learn and remember. Now Li-Huei Tsai, Picower Professor of Neuroscience at MIT, has uncovered an enzyme that is key to that protein's activity.

Cognitive 'fog' of normal aging linked to brain system disruption

Comparisons of the brains of young and old people have revealed that normal aging may cause cognitive decline due to deterioration of the connections among large-scale brain systems.

Brain systems become less coordinated with age, even in the absence of disease

Some brain systems become less coordinated with age even in the absence of Alzheimer's disease, according to a new study from Harvard University.

Scientists characterize Alzheimer's neurotoxin structure - potential new treatment approaches

Amyloid plaques, the hallmark of Alzheimer's disease, are clumps of fiber-like misfolded proteins which many experts think cause this devastating neurodegenerative disease.

Hydrogen sulfide provides clues to a longer life

Hydrogen sulfide, or H2S, the chemical that gives rotten eggs their sulfurous stench - and the same compound that researchers at Fred Hutchinson Cancer Research Center successfully have used to put mice into a state of reversible metabolic hibernation - has now been shown to significantly increase life span and heat tolerance in the nematode worm, or C. elegans.
